ABSTRACT:
A conventional pocket for delivering signatures in a bindery line is modified by providing a lift plate which is hinged to the leading edge of the pocket's signature support tray. A suitable actuator under control of the system's computer is made to raise and lower that lift plate, depending upon the number of machine cycles which will be executed before that particular pocket will be called upon to deliver a signature to the magazine being assembled. If more than a predetermined number of machine cycles will take place before a signature must be delivered, the actuator lifts the lift plate and, in doing so, elevates the leading edge of the signature stack to the point where the lowermost signature is positioned out of contact with the hopper's separator disc. This prevents unwanted abrasion and marring of signatures.
